This plugin was written for L4D2, and although I have tried to do this same function in L4D1, I have not been successful, I would like to know if someone can help me with the equivalents of these 2 values in L4D1:

L4D_GetVersusMaxCompletionScore
L4D_SetVersusMaxCompletionScore

Or some way to be able to do this same function in L4D1.

PHP Code:
#pragma semicolon 1

#include <sourcemod>

Need to find the "VersusMaxCompletionScore" offset in L4D1 binary, if it exists. Probably should have posted this in Left4DHooks thread.

Edit: Might be "944" on Linux. Left4DHooks would have to be modified to allow this native to be used. If you verify that's the correct offset then I'll update the plugin.

Found in "CTerrorGameRules::GetVersusMapMaxScore" which I'm guessing is the right place.

It did not occur to me to post in the Left4DHooks thread, but I will take it into account next time, even so I have already tried, that is why I ask for help, since I have not found anything that works, and here are the most experts in these topics.

Can someone help me with this ?, I remember seeing someone say that they knew all the binaries of L4D1, but I can not find it anywhere.

To better understand what I'm looking for, go through this thread:

It's hard to find "CTerrorGameRules::GetVersusMapMaxScore" on Windows since it's not used by the game at all and there's nothing in the function to reference.

How did you get that value?
PHP Code:
int __cdecl CTerrorGameRules::GetVersusMapMaxScore(CTerrorGameRules *thisint a2)
{
  
int result// eax

  
result 0;
  if ( (
unsigned int)(a2 1) <= )
    
result = *((_DWORD *)this a2 235);
  return 
result;

Is "a2" supposed to equal "1"? How would one know?
4 * (1 + 235) = 944 ?
or
(4 * 235) + 4 = 944 ?

Please don't create multiple threads to ask the same question. I have merged these 2.

This is what I do. But on Linux it had the 944 byte in hex before viewing the pseudocode so I copied it from that without doing the math.

I think windows offset will be +4. Have to test. Let me know and I'll add into Left4DHooks next update. I don't have time right now to test it out. But windows could be the same or, +8, +16, +20 etc. Would have to test with them all to find the right one, or using L4D1 structs to find the offset which Diswar1 converted/created for L4D1. Not sure if this variable is covered since I did look at the structs to retrieve a bunch of offsets when creating Left4DHooks.

PHP Code:

Linux
:
GetVersusMapMaxScore 0x3B0 current_map_number g_pGameRules

BHaType and I arrived at the same conclusion:
PHP Code:
"VersusMaxCompletionScore"
{
    
"windows"    "952" //Found via "m_iVersusMapScoreMax" string
    
"linux"    "944"

Looking at it, it may be changeable using GameRules_SetProp.

I understand Silvers, thanks for your help, if you add this to left4dhooks, I will take care of testing it myself, I will report any errors.

I also appreciate:

- Psyk0tik
- BHaType
- cravenge

For joining and collaborating with this publication, you are of great help, it is a project that I am doing, and I will not forget you when everything is finished, thank you very much.

Here is a version with support for "*VersusMaxCompletionScore". When I tried on Windows it returned 0 and all the addresses around there (searched with sm_ptr) did not correspond to the max score value. I don't have more time to try right now.

Will be added to Left4DHooks later today.
